摘要
岩体通常被弱面所切割、分离，岩体结构的稳定性与弱面性质密切相关，离散元方法是对岩体进行形变分析计算的方法之一。作者介绍了该方法的基本计算步骤并以预应力锚杆为例进行了应力、应变计算推导，为边坡加固、围岩支护提供了一种可靠的计算方法。
The rock mass is divided usually by the fractures or joints,whose stability is dependingon the properties of the fractures.The distinct element method is one of the methods used tocalculate the stress and defOrmation. The article presents the foundamental principles of thismethod and gives the formulations in the case of the prestressed bolt.It is a useful methodfor slope stability and tunneling engineering analysis.
